Anybody else get mixed messages from an ex?

My (I assume) ex says that we have no relationship anymore but yet she still emails and calls, and also returns my kisses. I wish I knew what was going through her mind but she's not telling. We were high school sweethearts and have lived together twice in the past, including now.

I feel she is my soulmate but I can't get her to talk, or go to counseling with me. She thinks God is "fixing" her.

Any advice?
